There's plenty of games that actually perform worse with SLI setups, the game has to be programmed to take full advantage of SLI, or at the very least have a profile made by Nvidia to gain a minimal performance boost.
That's nVidia ... you're better of with Ati's SLI-variant (Crossfire), which doesn't need 'special' settings.
And even if it performs worse ... it's only a driver-update away.
It's not far from how Ageia will perform, either the game will use it or it won't.
IMHO Ageia's performance should be questioned.
We've seen 'great' demo's of the Karma-engine before UT2kx was released.
In the end the engine proved too impractical to use in the 'real world'.
The good thing about Ageia is that UE3 uses it, that alone is a good chunk of future games, and there's rumors that Valve's Steam engine is following suit.
The bad thing is that they can't assume that everyone has that chipset.
Consider the fact that the first retail-versions of those cards sell at $200+ a piece I'd say it's a given.
As a result they can't take advantage of its feature-set and we won't see anything more complicated than current Karma-enabled features in UT2kx-maps.
I'd compare it to playing UT'99 with a Voodoo-card or with pure software-rendering.
It'll run, but you certainly won't like it unless you're mad enough to buy the hardware. And I seriously doubt reviews of UT2k7 can convince the *average* gamer that it's worth the money, unless there are some really good PhysX-enabled levels to play (on servers).
